I was looking up anime songs and jrock stuff, etc. I eventually found this song JAM Project - THE GUARDIAN. The first three things that came to mind when I heard this song were: Dragon Ball Z, Megaman and martial arts. So I searched the song in youtube and found this vid:

Words...cannot express the feelings I felt as I watched/listened to this song/vid...I'd say eargasm, but its a little more than that. There's just something nostalgic about it that makes think I watched it as a child or something. Dang I should look this up...

I don't think anyone actually mentioned NANA, which is sad, but my favourite would have to be in NANA:-Ending 1: A Little Pain-Opening 2: Wish-Ending 3?: Starless Night-Ending (forgot number): Winter Sleep-Insert song: Recorded Butterflies

You noticed that these are all from Olivia inspi Reira (Olivia is my goddess)- I like her better than Anna, but I love Anna too, especially Rose and Lucy. I also love the Death Note 1 opening and ending as well as Paradise Kiss opening.

edit: forgot to mention Claymore's first opening called Raison de etre (sorry for the spelling) by Nightmare- I love them too

Opening:Core Pride by Uverworld (Ao No Exorcist 1st OP)Kuusou Mythology by Yousei Teikoku (Mirai Nikki OP)Haruka Kanata by Asian Kung-Fu Generation (Naruto 2nd OP) This will be my all time favourite one cause this is the first OP I saw in Naruto
